where <math>\textstyle\varphi</math> is the implicit mapping embedded in the RBF kernel.
One way to construct such a ''z'' is to randomly sample from the [[Fourier transformation]] of the kernel.<ref>Ali Rahimi and Benjamin Recht (2007). [http://www.eecs.berkeley.edu/~brecht/papers/07.rah.rec.nips.pdf "Random features for large-scale kernel machines"]. ''Neural Information Processing Systems''.</ref> Another approach uses the [[Nyström method]] to approximate the [[eigendecomposition]] of the [[Gramian matrix|Gram matrix]] ''K'', using only a random sample of the training set.<ref>{{cite journal |authors=C.K.I.
